EnergyConsumption Data

(eventually to be added to energyconsumption.org)


The data I have up at http://energyconsumption.org/data.txt is a text file. That makes it hard for other people to add data and see it online in a timely way, though I do try to update it promptly when I get new data.


Data collection Directions

EC's Contribute [your data] page also suggests several ways of measuring a computer's energy use, though it neglects graphics cards which have become much more important in recent years.


We don't have a "meter used" column, but any low wattage measurements taken with an original Watts Up? should be considered suspect. I have a "great" fan with a really misleading power factor which I will use to test my original Watts Up? The KaW and Watts Up? "2.0" are considered accurate for the purposes of this page. Wattages under 2W are probably within the error range. We should re-check the error accuracy data from the KaW instruction sheet.

(need a schema that can encompass refridgerator / major appliance data)

(if people actually start contributing, we should have a separate "new data" or "contribute data" page)
